Given the lead time of building a fab and producing components, trying to incentivize the production of specific devices that happen to be in short supply right now is probably not a great plan. The market does a pretty good job of sending demand signals to producers, faster than the government can generally create and pass incentivizing legislation. But if you don't have the production capacity in the first place, encouraging that to be built out (which is a long-term process) does seem like something where government can meaningfully intervene.
